Disease Risks ·Posed By Wild Birds Associated With Agricultural Landscapes, Larry Clark

United States Department of Agriculture Wildlife Services: Staff Publications

There are over 1,400 cataloged human pathogens, with approximately 62% classified as zoonotic (Taylor et aI., 2001). While most evidence of direct transmission of pathogens to humans involves domestic and companion animals, the reservoir for most zoonoses is wildlife, yet there are relatively few well-documented cases for the direct involvement of transmission from wildlife to humans (Kruse et aI., 2004). In part, this absence of evidence reflects the mobility of wildlife, the difficulty in accessing relevant samples, and the smaller number of studies focused on characterizing wildlife pathogens relative to the human and veterinary literature (McDiarmid, 1969; Davies et aI., …

Efficacy Of Ropel® As A Coyote Repellent, Elizabeth A. Miller, Julie K. Young, Scott Stelting, Bruce A. Kimball

United States Department of Agriculture Wildlife Services: Staff Publications

We examined the repellency of a commercially available animal repellent to determine the efficacy of its application to objects that are attractive to coyotes (Canis latrans). Specifically, we aimed to both prevent chewing behavior by coyotes on a nylon-like strapping material, which is used to construct barrier-arresting systems on military airstrips, and determine the ability of the solution to prevent the animals from repeating the undesired behavior. We mixed Ropel® Animal and Rodent Repellent with a liquid latex sticker to form a 2% latex and 98% Ropel solution. We used a 2% latex and 98% water solution as …

Memory-Based Quantity Discrimination In Coyotes (Canis Latrans), Salif Mahamane, Kevin L. Grunig, Joseph Baker, Julie K. Young, Kerry E. Jordan

United States Department of Agriculture Wildlife Services: Staff Publications

Previous research has shown that the ratio between competing quantities of food significantly mediates coyotes‘ (Canis latrans) ability to choose the larger of two food options. These previous findings are consistent with predictions made by Weber‘s Law and indicate that coyotes possess quantity discrimination abilities that are similar to other species. Importantly, coyotes‘ discrimination abilities are similar to domestic dogs (Canis lupus familiaris), indicating that quantitative discrimination may remain stable throughout certain species‘ evolution. However, while previously shown in two domestic dogs, it is unknown whether coyotes possess the ability to discriminate visual quantities from memory. …

Using Novel Spatial Mark–Resight Techniques To Monitor Resident Canada Geese In A Suburban Environment, M. Elizabeth Rutledge, Rachel Sollmann, Brian E. Washburn, Christopher E. Moorman, Christopher S. Deperno

United States Department of Agriculture Wildlife Services: Staff Publications

Context. Over the past two decades, an increase in the number of resident (non-migratory) Canada geese (Branta canadensis) in the United States has heightened the awareness of human–goose interactions.

Aims. Accordingly, baseline demographic estimates for goose populations are needed to help better understand the ecology of Canada geese in suburban areas.

Methods. As a basis for monitoring efforts, we estimated densities of adult resident Canada geese in a suburban environment by using a novel spatial mark–resight method. We resighted 763 neck- and leg-banded resident Canada geese two to three times per week in and around Greensboro, North Carolina, …

Exposure Of Feral Swine (Sus Scrofa) In The United States To Selected Pathogens, John A. Baroch, Carl A. Gagnon, Sonia Lacouture, Marcelo Gottschalk

United States Department of Agriculture Wildlife Services: Staff Publications

Feral swine (Sus scrofa) are widely distributed in the United States. In 2011 and 2012, serum samples and tonsils were recovered from 162 and 37 feral swine, respectively, in the US to evaluate exposure to important swine endemic pathogens. Antibodies against porcine reproductive and respiratory syndrome virus (PRRSV) and porcine circovirus type 2 (PCV2) were found in 2.5% and 25.3% of tested sera, respectively. Positive serological reactions against Mycoplasma hyopneumoniae and Actinobacillus pleuropneumoniae have been detected in 19.7% and 69.7% of animals. More than 15% of animals presented antibodies against these 2 pathogens simultaneously. Most animals were also seropositive for …

Risk Factors Associated With Enteric Septicemia Of Catfish On Mississippi Commercial Catfish Farms, Fred L. Cunningham, S. W. Jack, David Hardin, Robert W. Wills

United States Department of Agriculture Wildlife Services: Staff Publications

A gram-negative bacterium, Edwardsiella ictaluri, is the cause of enteric septicemia of catfish (ESC), which is one of the most prevalent bacterial diseases in farm-raised catfish. The objective of this study was to identify risk factors associated with ESC mortalities and are reported by farm personnel. To identify risk factors a catfish management database was developed. The odds ratios (OR) of the final multivariable logistic regression model were: (1) volume of the pond (OR, 0.56), (2) interval from harvest until a mortality event (OR, 1.49), (3) interval from stocking until a mortality event (OR, 0.52), (4) nitrite measured within 14 …

Effects Of Gonacon Immunocontraceptive Vaccine In Free-Ranging Female Rocky Mountain Elk (Cervus Elaphus Nelsoni), Jenny G. Powers, Ryan J. Monello, Margaret A. Wild, Terry R. Spraker, James P. Gionfriddo, Terry M. Nett, Dan L. Baker

United States Department of Agriculture Wildlife Services: Staff Publications

Duration of efficacy and prevalence of side-effects associated with GonaCon Immunocontraceptive Vaccine (GonaCon) in free-ranging female elk (Cervus elaphus) are unknown. In January 2008, we captured 120 mature female elk in Rocky Mountain National Park (CO, USA), determined pregnancy status, and randomly assigned them to treated (n=60; 1.5 mL of GonaCon) or control (n=60; 1.5 mL of saline) groups. During the following 3 winters we recaptured, collected blood for antibody concentrations, and euthanized 10–20 elk in each group. At necropsy, we determined pregnancy and collected tissues from organs associated with the hypothalamic–pituitary–gonadal axis. We …

The Evolutionary Dynamics Of Transcription Factors, Operators, And Their Target Genes Across Prokaryotes, Marc Del Grande

Theses and Dissertations (Comprehensive)

In prokaryotes, transcriptional regulation commonly involves a transcription factor (TF) binding to a particular conserved sequence of nucleotides (operator). Binding elicits a transcriptional response, either activation or repression. The evolution of gene regulation has been identified as a primary driver of species diversity, making it an important area of research. This work examined the dynamics of the interactions between TFs and operators, and TFs and their primary target genes in attempt to assess the rapid evolution of transcriptional regulatory networks (TRNs) across a diverse set of prokaryotes. Using software packages, operator sequences from Escherichia coli K12 were compared to every …

Nesting Ecology Of White-Throated Sparrows (Zonotrichia Albicollis) : The Effects Of Variation In Clutch-Initiation Date And The Application Of Prescribed Fire On Nesting Success, Melissa Olmstead

Theses and Dissertations (Comprehensive)

The study of nesting success is one of the most widely-used methods for examining the factors governing recruitment in birds. Many ecological influences act together to increase or decrease nesting success, and knowledge of these mechanisms is crucial for determining the habitat or conservation requirements of a given species. One ecological influence is the timing of breeding, which in many species is related to a decline in nest success later in the breeding season. Much of the research on this subject has focused on cavity-nesting species, and the hypothesis that this seasonal decline is caused by a mismatch between clutch-initiation …

Investigating The Persistence And "Naturalization" Potential Of Salmonella In Non-Host Environments Using Culture-Based And Molecular-Based Fingerprinting Techniques, Robyn L. Morrison

Theses and Dissertations (Comprehensive)

Recent studies suggest the potential exists for enteric microorganisms to become “naturalized” to the complex natural environment through maintenance of their populations via replication and adaptation to the stress imposed by their external surroundings. The aim of this research was to better understand the potential for antimicrobial resistant (AMR) Salmonella to become “naturalized” and the physiological adaptations that allow for non-host survivability as reflected by AMR and community profiling. To better elucidate the prominent factors leading to a “naturalized” condition, two approaches were taken: 1) survey-based field research to gain perspective on the prevalence of AMR Salmonella isolated from variously …

A Computational Study Of Small Gold Clusters With H2s, Thiols, H2o, And Alcohols, Silvija C. Smith

Theses and Dissertations (Comprehensive)

Alkane thiols, RSH, are commonly used in aqueous solution to stabilize and prevent aggregation of gold clusters, Au_n. Initially a RSH-Au_n complex is formed and, subsequently, there is hydrogen atom transfer to form a RSAu_nH complex. We examine the rate of this reaction for small neutral gold clusters, with n=1-2 and short-chain thiols with R = H, CH₃, and CH₃CH₂, using transition state theory. The comparison of DFT (with the functionals, BP86 and M06-2X), and MP2 was performed. A pseudopotential was employed to account for the large relativisitic effects …

Response To Mental Health Calls: The Frontline Perspectives Of Police Officers, Communicators And Administrators, Sarah C. Dougall

Theses and Dissertations (Comprehensive)

Abstract

OBJECTIVES: The purpose of this study was to examine the lived experiences of frontline police personnel of a mid-sized police service in Southern Ontario. As the prevalence of mental illness increases, so do the calls for assistance to police services. Police officers often find themselves on the frontline and are often the first responders to mental health calls when an individual is in crisis (Wells & Schafer, 2006). With the majority of current research being quantitative in nature, this qualitative study allowed the voice of frontline police personnel to be heard in order to provide a complete picture of …

Vocabulary And Reading Comprehension Intervention: A Focus On Students In The Late Elementary Grades, Melissa L. Dol

Theses and Dissertations (Comprehensive)

Literacy skills are key to success in school, career, and everyday life. Despite school curricula being strongly focused on literacy development (Ministry of Education, 2006), many children continue to fall behind the expected literacy skill levels for their grade (Education Quality and Accountability Office, 2012a, 2012b; National Center for Education Statistics, 2011). The present study evaluated a literacy intervention, Better Reading for School Success (BRSS), accompanied by a parent/guardian literacy workshop and weekly tips regarding how parents and/or guardians can promote literacy skill development at home. The BRSS was also evaluated as a subsection of family literacy afterschool programs, ‘Get …

A Side Of Justice Rarely Seen: Professional Perspectives Toward Youth Justice And Sentencing Procedures In The Exploratory Context Of Canada And Russia, Serge Lokshin M.A.

Theses and Dissertations (Comprehensive)

This thesis contributes to the growing body of literature on comparative youth justice and policy. By analyzing dilemmas faced by youth in justice systems from the perspective of Canada and Russia, the study argues that professional outlooks have a considerable significance for understanding the legal system and its function, and play an important role in shaping judicial administration concerning juveniles. An investigation into professional perspectives on youth justice is used to formulate an understanding of the issues for young people within the legal systems of the respective regions, the sentencing procedures, and the social and procedural contentions facing youth on …

The Transient Collaboration Model: Theory Building, Structural Formation, And Operationalization, Adrian C. Tan

Theses and Dissertations (Comprehensive)

This thesis seeks to describe the Transient Collaboration Model as a business model, its underlying theoretical principles, its empirical evidence, and its types of possible collaboration structures. The research seeks to determine how companies may build sustained competitive advantages through the structural design of their collaboration associations as a strategic option. Companies' ability to retain long-term competitive advantages is limited in more unpredictable environments. Companies could not afford to internally build and hold all the possible varieties and quantities of resources and capabilities to build future competitive advantages. Collaboration can provide companies with access to multiple partners with diverse resources …

Integrated Spatial Analysis Of Volunteered Geographic Information, Haydn Lawrence

Theses and Dissertations (Comprehensive)

Volunteered Geographic Information (VGI) is becoming a pervasive form of data within geographic academic research. VGI offers a relatively new form of data, one with both potential as a sensitive way to collect information about the world, and challenges associated with unknown and heterogeneous data quality. The lack of sampling control, variable expertise in data collection and handling, and limited control over data sources are significant research challenges. In this thesis, data quality of VGI is tackled as a general composite measure based on coverage of the dataset, the evenness in the density of data, and the relative evenness in …

Effects Of Salinity And Dissolved Organic Matter On Cu Toxicity To Americamysis Bahia In Estuarine Environments, Rabia Nasir

Theses and Dissertations (Comprehensive)

As salinity increases the geochemical speciation of Cu is altered as a result of organic/inorganic complexation/competition. Such salinity changes may further challenge the osmoregulatory capabilities of euryhaline organisms. This chemical-biological interaction complicates the understanding of the impacts of Cu in estuarine waters. Dissolved organic matter (DOM) has been widely established to be an important modifier of Cu toxicity in freshwaters however its effectiveness in modulating Cu toxicity across the range of salinities that occur in estuarine conditions has not been studied in a systematic manner. Site to site differences in DOM quality with respect to the potential for toxicity mitigation …

Chandler, Kelsey M. Christian, Leah Mcalistar-Shields, Stephen P. Thompson, Magdalena A. Denhem, Anthony J. Onwuegbuzie

Librarian and Staff Publications

The purpose of this collective case study was to use a critical dialectical pluralistic (CDP) philosophical lens to investigate select doctoral students’ perceptions about the challenges that they encountered while in a doctorate program and the coping strategies that they found effective in mitigating these challenges. A major goal of CDP is to empower research participants maximally by giving them the role of participant-researchers. Participants were 10 doctoral students enrolled at a Tier-II university in the United States, who were selected via convenience sampling. Each student participated in a face-to-face interview with a member of the research team—consistent with a …

Narrowing The Gap Between Rights And Resources: Finding A Role For Law Students In Court-Annexed Resource Centers, Faith Mullen

Scholarly Articles

This article relates the experience of law students from The Catholic University of America providing assistance in the Small Claims Resource Center during the past eight years. During this time, the District of Columbia Bar Pro Bono Program has played a pivotal role in the development and the ongoing success of court-annexed resource centers in the District of Columbia. They have recruited law firms and legal services providers (including law school clinics) to staff the resource centers, sought changes in the rules of professional responsibility, and developed intake forms and model pleadings. Their steady oversight, provided by knowledgeable and resourceful …

Bridging The Gaps In Property Theory, Adam J. Macleod

Scholarly Articles

Though several others can rightly be said to have done as much, no one has done more to rehabilitate the idea of property as a meaningful normative concept than James Penner and Henry Smith. That the two of them have edited a collection together is a substantial reason to read it. That the collection contains contributions from many of the best property theorists is another. The introduction to the book sets the ambitious goal of identifying what needs explaining in the ‘broad space that lies between’ the philosophy of property and scholarship about particular legal doctrines. For anyone interested in …

Quantitative, Qualitative, And Collaborative Methods: Approaching Indigenous Ecological Knowledge Heterogeneity, Jeremy Spoon

Anthropology Faculty Publications and Presentations

I discuss the use of quantitative, qualitative, and collaborative methods to document and operationalize Indigenous ecological knowledge, using case studies from the Nepalese Himalaya and Great Basin. Both case studies applied results to natural and cultural resource management and interpretation for the public. These approaches attempt to reposition the interview subjects to serve as active contributors to the research and its outcomes. I argue that the study of any body of Indigenous knowledge requires a context-specific methodology and mutually agreed upon processes and outcomes. In the Nepalese Himalaya, I utilized linked quantitative and qualitative methods to understand how tourism influenced …
